Plants are having many constituents which contain medicinal properties and they act as reservoir for such valuable compounds. In this article we are exploring the phytoconstituents and antioxidant potential of aqueous extract, prepared from hard shell of fruit of Aegle marmelos (Bael). The aqueous extract (AE) was analyzed for phytoconstituents by phytochemical profiling and by measurement of total phenolic content. The potency of extract was evaluated through various in-vitro assays like total reducing power, DPPH free radical scavenging activity, superoxide radical scavenging activity, hydroxyl radical scavenging activity, lipid peroxidation inhibition and metal chelation activity. Antimicrobial activity and hemolytic activity was also evaluated to assess its potential for further use in therapeutics.
